摘要： An electro-hydraulic control system is provided with a diagnostic system that uses extensive multiplexing of pressure switches to reduce the number of required components. The control system includes a controller with a pressure switch diagnostic system having first, second, third and fourth pressure switches each having a high and a low logic state, first and second logic valves each movable between a respective first position and second position, and first, second, third and fourth trim valves each movable between a respective first position and second position. The pressure switches are multiplexed to report one of the high and low logic state to the controller in accordance with a relatively high and low fluid pressure, respectively, at different ones of the trim valves and logic valves, thereby enabling a determination of a change in or failure to change position of the respective the trim valves or logic valves.

摘要： A transmission includes an electro-hydraulic controller that includes redundancy in the hydraulic circuit that permits single fault failures to be compensated for by changing the flow path of hydraulic fluid to bypass the single fault failure. The redundancy results in the ability of the transmission to maintain full operation in all modes.

摘要： An apparatus for controlling a variator having at least one roller between two toroidal disks may include at least one actuator responsive to fluid pressure at separate high side and low side fluid inlets thereof to control torque applied by the at least one roller to the disks. First and second variator switching valves may each receive a first fluid at a first pressure and a second fluid at a second lesser pressure. The first and second variator switching valves supply the first fluid to the high side fluid inlet and the second fluid to the low side fluid inlet during two of four different operational states together defined by the variator switching valves, and supply the second fluid to the high side fluid inlet and the first fluid to the low side fluid inlet during each of the remaining two of the four different operational states.
